Abdul Mazid Sardar, a madrassa teacher, cut the ears of the students --- aged between six and nine --- for failing to learn Islamic verses.
He was finally stopped by other members of the staff alerted by the children's screams.
Irate relatives then mobbed the school and assaulted Sardar, who was later hospitalized. "As the students were creating chaos I just wanted to scare them by showing the scissors," Sardar told journalists from his hospital bed. "Probably at the time an evil force mounted on me."
Authorities said he has been sacked.
